tinted tant t i v. anni f @time p IMPROVEMENT Il STAIR-RODS.

The Schedule referred to in these Letters Patent and making part o f the same -To all whom it ma/y conce/rn Be it known that I, H. UHRY, of the city of New York, in the county of New York, and. State of New York, have invented certain Improvements in Stair- Rods, and in the manner of fastening the same to the stairs; and I do hereby declare that the following is a full and exact description thereof', which will enable others skilled in the art to make and lise my said invention, reference being had to-the accompanying drawings, forming part of this specification, and markedD at upper right-hand corner, to distinguish said drawings from others for similar invention, already filed for examination in the United States Patent Oice by myself.

This invention relates t0 the class of stair-rods which are made of wood.

It is designed, more especially, to obtain a secured fastening, entirely concealed from view, leaving to the rod, when fastened in its place, the appearance of being held there by two large-headed nails, in old style, axoiding the exhibition of any metallicV fastenings.

The invention consists of the combination of the wooden rod with a rotary hollow-beadv catch, or bolt, and a T-headed, triangular-h eaded, or L-headed screw, or nail, more fully described below, by means of which the said rod is fastened to the stairs; and

It furthermore consists in making the end of the rotary bolt pointed, to serve as marker, or gauge, forindicating the place on the stairs where the screws or nails are to be driven.

In my drawings- Figure l represents a top view oi' one of my improved stan-rods, when turned back foremost, and used as a gauge for marking the place of the screws on the stair-case M;

Figure 2 is a front view of my improved stair-rod, as seen when in place;

Figure 3 is a front view (full size) of a piece of the same, showing the fastening;

Figure 4 is a sectional view of the same through xyx, to show details;

Figure 5 is a view of the rotary bolt, or catch, as seen from the back of the rod; and

Figures 6 and 7 are modifications of the shape of the catch-plate and hook, for the sake of illustrating the same.

A is the wooden stair-rod, which may be made of any desired wood and shape for ornamentation, but

` which has, at the points where it is intended to be fastened tothe stairs, holes, C O, and cavities, D D, made by boring from the back of the rod, with a bit of proper size to form the cavity D to a proper depth, then, with a smaller bit, iinishing the work, by making the hole C entirely through the thickness of the said'stair-rod.

M represents the riser of the stairs, to which the rod is to be applied.

E is a rotary catch, or bolt, having a hollow head, made to lit in the circular cavity D, where it may be turned by applying the lingers to the bolt-nut G, which is fastened to the bolt E by the pin g.

The hollow head ofthe bolt E is covered with a sheet of metal, or catch-plate, a, properly fastened to the said head, and having a perforation made therein of an oblongshape, to receive the head of the screw or nail T. y

T is a screw or nail, having'its head of propel' shape to correspond with the catch-plate a, opening, so that when the head of said screw or nail is-passed through the same, and turned a sixth or aquarter of a turn on its axis, it will be fastened or lockedin the'hollow head of the bolt E. (In place of the screw T, I sometimes u se a screw-eye.)

The piece E is introduced in the cavity D and C of the rod A, and fastened thereto by the washer G, being securely fixed to thel piece E by the pin g, but the piece E has a free rotary motion 0n its own axis, in the marked the places, as above described, the screws T are driven in, and the rod being turned the other way,

and held by the nuts G G, the rotary bolts E E are Aturned until the holes inthe plates a et enter or slip over the heads of the screws l T, when, by a slight turning of the bolts E E, the rod is eiectually fastened.

Claim.

The combination of the wooden stair-rod A. with the rotary bolt E and the screw or nail T, arranged substantially as, and operating in the manner herein set forth.
